Letters .Patent No. 102,175, datedApr/il19, 1870.

IMPROVMENT IN APPARATUS FOR COOLING GRAIN.

The Schedule referred to in these Letters Patent and making part of thesame To whom tt may concern.-

Be it known that 1, SOLOMAN A. STEnBINs, of Toledo, Lucas county,'Ohio,have invented anewand useful Improvement in Apparatus for Cooling Grain,or preventing grain in bulk from heating and spoiling, and, also,freeing it from must; and I hereby declare the following to be a full,clear, and exact description of the construction and operation ofthesame, reference being had to the accompanying drawings and to ltheletters and figures thereon, which are hereby made a part of thisspecification.

Like figures and letters represent-like parts in the several drawings.

Figure 1 represents a sectional view of a grain-bin, with my improvedcooling apparatus therein.

Figure 2 represents a view, in perspective, of my cooling apparatusdetached.

A represents the general construction and shape of the bottom and sidesof a bin.

B represents a pelforated metal cylinder.

O represents the supports of the same.

D represents pipes which pass through the sides or bottom of the bin,and are attached to the cylinder B.

lo enable others to make and construct my cooling apparatus, I describeits construction and operation, as follows:

Gis a grain-bin or holder, or, it may be a boat or vessel, ofthe shapeand size ordinarily used in grain warehouses, or for carrying grain,into which is placed the cylinder B, made of sheet-metal, withperforations in its periphery and ends, as closely together as thestrength of -the metal'required for the support of the grain will allow,and of such size as will not permit the grain to be cooled to passthrough. This cylder may be of 'any diameter or length required by thesize of the bin or vessel and bulk of grain, and is placed upon thesupports C, which are secured to the sides or bottom of the bin orvessel. One or more openings are made in the cylinder, wherever it maybe most convenient, with suitable arrangement for attaching the pipes D,for the passage of currents of air through the pipes into the cylinder,which current of air is'generated by means of bellows, or otherapparatus. The air thus conveyed into the cylinder or reservoir isforced through its perforations into the grain, covering it andpermeating its bulk, reaching every part thereof', cooling and freeingit from must, .preserving it, and preventing its spoiling While kept inbulk without means of ventilation. The apparatus for forcing the air maybe placed'where convenient for connecting the pipes D therewith, and maybe operated by means of hand, horse, steam, or other power.

lVhat I claim, and desire to secure by Letters Patent, is-

lhe combination of the bin AI or its equivalent, perforated cylinder Bwith perforated ends, supports C, and pipe D adapted to receive acurrent of air from the outside of the bin, substantially as and for thepurpose hereinbefore specified.
